Answer:
576 adults
Step-by-step explanation:
The 5 part of the ratio relates to 720 children, then
720 ÷ 5 = 144 ← value of 1 part of the ratio , then
4 parts = 4 × 144 = 576 ← number of adults

Answers: <u>
x = 2 and x = 10</u></h3>
========================================================
Explanation:
Draw a horizontal line through 10 on the y axis. This is because R(x) = 10 is the same as y = 10. The output of the function is the y value.
See the diagram below.
The horizontal line crosses the parabola at two locations. From those points, draw a vertical line straight down to the x axis. Note how we land at x = 2 and x = 10. This means that R(2) = 10 and R(10) = 10.
Hello from MrBillDoesMath!
Answer:
P = ( sqrt(2)/2), sqrt(2)/2 )
Discussion:
The circle has a radius of 1 as passes it passes through the point (1,0). P makes an angle of 45 degrees with respect to the positive x axis, so by the Pythagorean theorem (or equivalently, trigonometry),
P = (x,y) = ( [email protected], [email protected]) = (1 cos(45), 1 sin(45)) =
( sqrt(2)/2), sqrt(2)/2)
Thank you,

Answer:
total number of students is 25
AIZA AND GLAIZA came 60% of the 25 students that is 15th position
A) therefore students which came below them were= 10
B) Students who has scored greater than them were=> 15-2=13 (as they niether got less than 12 nor more than 12.)
